[jira] [Commented] (CASSANDRA-2614) create Column and CounterColumn in the same column family
[ https://issues.apache.org/jira/browse/CASSANDRA-2614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=13067072#comment-13067072 ] Sylvain Lebresne commented on CASSANDRA-2614: - Now that CQL allows for user side timestamp (which it should, no question asked), that row deletion problem covers CQL too (actually no yet, because of CASSANDRA-2912, but that's just a bug). bq. Is it possible (when Deleting, inside a thrift Mutation) to loop through all the columns that need to be deleted That doesn't really help. The problem is with full row deletion. If you have a row with regular columns and with one declared counter column 'c1', then if you get a row deletion, you can insert a deletion with server side generated timestamp for 'c1', but what for the rest of the row ? If you insert the row tombstone, it will still screw up c1. One possible solution I see would be to have specific row tombstones that only act on regular columns and others that only act on counter columns. Row deletion would then adds both kind of tombstone with the right timestamp each time. But we're talking internal format change, so that would postpone this to 1.0 at best (considering we want to do it). Until that, we still have the possibility to disallow row deletion on mixed regular/counter column family. create Column and CounterColumn in the same column family - Key: CASSANDRA-2614 URL: https://issues.apache.org/jira/browse/CASSANDRA-2614 Project: Cassandra Issue Type: New Feature Components: Core Reporter: Dave Rav Assignee: Sylvain Lebresne Priority: Minor Fix For: 0.8.2 create Column and CounterColumn in the same column family -- This message is automatically generated by JIRA.

For a Deletion (inside a thrift Mutation), the timestamp is required to be set if the CF is a regular one, but not if it is a counter CF. But more importantly, for counter CF, the timestamp should be a server generated timestamp. If we allow row to mix counters and regular columns, then when facing a Deletion for a full row, there is no way to accommodate those two requirements. It would kind of be a shame of not doing this because of Deletion, but I don't see a good way around this (other than changing the API, which would move that ticket to 1.0).

Sylvain Lebresne commented on CASSANDRA-2614:
-
To be more specific, the idea is for instance to allow counter in a non-counter
CF with something like
{noformat}
column_metadata = [
{column_name: first, validation_class: UTF8Type},
{column_name: last, validation_class: UTF8Type},
{column_name: friends, validation_class: CounterColumnType} ];
{noformat}
In which case we know when we expect a counter and when we do not. Moreover the
code already handle mixing counter and non counter mutations in a batch_mutate,
so most of the handling of the different write path is already there. We will
still have to extract the counter column for this so that it goes through the
correct write path, but that can be done while we translate the thrift
structures to our internal representations.

Several problems 1. If a column is initially created as a counter, but a non-counter insert comes through what do we do? We can't give the inserter an error unless we introduce reads in the write path. 2. The write path is somewhat different for the two kinds of columns. Counters don't really respect CLs the same way normal columns do. create Column and CounterColumn in the same column family - Key: CASSANDRA-2614 URL: https://issues.apache.org/jira/browse/CASSANDRA-2614 Project: Cassandra Issue Type: New Feature Components: Core Reporter: Dave Rav Assignee: Sylvain Lebresne Priority: Minor Fix For: 0.8.1 create Column and CounterColumn in the same column family -- This message is automatically generated by JIRA.
